# reload is the rebuild. Cache-Control: no-store keeps a stale module from
# surviving that reload (see vite.config.js).

# --host binds to the LAN as well, so a phone on the same wifi can open the
# address vite prints as "Network" and test touch input on real hardware.

# The .wav files are the masters; the game loads the .mp3 next to them.
# MP3 because it is the one lossy format every current browser decodes
# without leaning on an OS codec - notably firefox, which has no AAC
# decoder of its own. Both are committed, so running the game needs no
# ffmpeg; this target is only for re-encoding after changing a sound.
